In this paper, a millimeter wave vertical transition with ultra wideband filtering function is presented. Compared with the traditional vertical transition, it not only has the vertical transition function, but also has ultra wideband millimeter wave filtering function. The simulated result shows that the proposed vertical transition has a good performance. The insertion loss in the center frequency...
In this paper, a substrate integrated waveguide (SIW) circulator with metallic-via inductive window is presented and investigated with simulation and experimental results, which can provide 20dB isolation with 13.7% fractional bandwidth at the center frequency of 9.41GHz. Besides, in order to connect with microstrip circuits, a compact SIW to microstrip transition with embedded feed-line is included...
